Description

Device for fastening a surface element

State of the art

The invention is based on a device for fastening a surface element, which consists of a support profile and a clip strip, according to the preamble of independent claim 1. When used in practice so far

Devices, a crescent-shaped extension attached to the clip strip, encompasses a tubular design on the carrier profile. In order to ensure stable securing of this type of fastening, an extension of the clip strip is supported on an extension of the

Beam profile. In this device, however, the clip strip is difficult to remove and usually cannot be removed from it without damaging the carrier profile. This can cause problems with the exchange, e.g. B. arise from broken windows from the device. Furthermore, this construction can result in an asymmetrical force run, which can lead to a greater one-sided load on the support profile and also on the frame in which the support profile is fastened. Advantages of the invention

The device according to the invention with the characterizing features of independent claim 1 has the advantage that the clip strip can be attached to the support profile in a simple manner by hand. Installation on site is therefore also possible. The device is simple with the help of z. B. a screwdriver again divisible. Furthermore, the

Bearing force of the surface element, e.g. B. a window or door or other wall structures evenly and symmetrically distributed over the support profile on the base support. Due to the elastic design of the ends of the legs of the clip strip and the support profile, it is possible to fasten surface elements of different thicknesses with one and the same device. In particular, surface elements that have a width of 1.5 to 8 mm can be fixed with one and the same device.

The measures listed in the subclaims allow advantageous developments of the device specified in claim 1.

FIG. 1 shows a section through a carrier profile as it is installed in a first carrier, while FIG. 2 shows a longitudinal section through a carrier profile as it is installed in a second carrier. Figure 3 shows a section through a clip strip and Figure 4 shows a schematic section through an assembled device with inserted Surface element. FIG. 5 shows a section through a modification of a clip strip.

Description of the embodiments

In FIG. 1, 10 denotes a support profile which is part of the device 11 shown assembled in FIG. The carrier profile 10 has a base part 14 which has a flat surface 13 and on which a surface element 15, as can be seen in FIG. 4, rests. At the bottom part 14 closes at an angle, for. B. inclined at 43 ° to the plane of the surface 13, a section 16 or 17, which merges into a parallel to the bottom part 14 support part 18 or 19. A side wall 20 or 21 adjoins the support part 18 or 19 perpendicularly thereto. A holding lip 22 is formed on the side wall 20 and has a relatively hard section 23 and a relatively soft or elastic section 24 located at the end of the holding lip 22. Section 23 can consist of hard PVC or PP (polypropylene), while section 24 can consist of soft PVC (polyvinyl chloride) or PTU (polytetraurethane). With the section 24, the holding lip 22 rests on the surface element 15. The second side wall 21 has a latching hook 25 at the end, which is directed toward the bottom part 14 or towards section 17.

On the bottom part 14, on the side 30 facing away from the surface 13, two legs 31, 32 are formed, which protrude into a groove 33 of a carrier 34. The two legs 31, 32 are designed to be elastic and have a pretension so that they rest on the side wall after installation in the groove 33. Furthermore, the legs 31, 32 have on the outside, ie on the side walls of the groove 33 facing side, two locking hooks 35, 36. The locking hooks 35, 36 are matched to one another so that the support profile 10 can be used with different groove sizes and thus different supports 34. The arrangement of the latching hooks 35, 36, in particular the distance from the base part 14, must be matched to the thickness of the carrier 34 having the groove 33. Furthermore, the carrier 34 used is matched to the size of the surface element 15 to be fastened.

If the carrier profile 10 can be used for two different carriers 34, the legs 31, 32 each have two latching hooks 35, 36. In FIGS. 1 and 2, the carrier profile 10 is shown inserted in two carriers 34, 34a of different sizes. 1 shows a larger carrier 34, which has an approximately 10 mm wide groove. If the two legs 31, 32 are inserted into this groove 33, the lowest, d. H. the detent hook 36 most distant from the underside 30 of the base part 14 for engagement with an undercut

38 in the groove 33 of the carrier 34. The second latching hook 35 has no direct fastening task. It lies against the side wall of the groove 33 of the carrier 34. The distance between the two locking hooks 35, 36 is adjusted so that the carrier 34 can rest fully on the locking hook 36, i. H. that the locking hook can reach completely behind the undercut 38, and that the two support parts 18, 19 also come to rest on the support 34.

The difference in Figure 2 is the installation of a

Carrier profile 10 shown in a smaller carrier 34a. This carrier 34a has, for. B. a groove width of only 8 mm. In this case, the other latching hooks 35 engage, ie the latching hooks 35 arranged closer to the underside 30 of the base part 14 on the undercut 38 of the groove 33 of the carrier 34 on. Again, the support parts 18, 19 rest on the carrier 34a. The legs 31, 32 protrude further into the groove 33 so that the latching hooks 36 are freely arranged there and do not perform any fastening tasks.

FIG. 3 shows a clip strip 40 which, as can be seen from FIG. 4, is used with the carrier profile 10 for fastening the surface element 15. The clip strip 40 has a leg 41, which has the function of the holding lip 22 in the carrier profile 10. The leg 41 has an elastic, soft upper section 42 and a relatively rigid, hard lower section 43. The sections 42 and 43 can be made of the same materials as the sections 23 and 24 of the retaining lip 22 of the carrier profile 10. The leg 41 has e.g. B. an incline of 20 ° - 60 °, in particular of 60 °, to the surface 13 of the bottom part 14 of the carrier profile 10. Two extensions 44, 45 are arranged at section 43 at a distance from one another. The distance here is so large that the side wall 21 can protrude between the two extensions 44, 45 and the locking hook 25

Side wall 21 can come into operative connection with a locking hook 47 formed on the inner leg 44. The outer leg 45 is designed such that it runs parallel to the side wall 21 in the assembled state of the clip strip 40 and the support profile 10 and is at least partially supported on the outer wall of the side wall 21.

FIG. 4 shows the device 11 in the assembled state and with the surface element 15 inserted. In the area element it can be, for. B. around a disc, e.g. B. act window, doors or partitions, panels and screens. The carrier 34 is to be understood here as a circumferential closed frame, which then z. B. is used in a wall construction. It is particularly advantageous in this device according to the invention 11 that the actual construction, ie the individual components, as shown in Figures 1 to 3, can be made on site. Here, the carrier 34 is used as a frame mentioned above in a wall. Then the surface element 15 is placed on the top 13 of the bottom part 14 of the carrier profile 10 with its end face. The surface element 15 rests with its edge on the holding lip 22 of the carrier profile 10 and presses the soft section 24 of the holding lip 22 somewhat back. This makes it possible

Place surface element 15 in the middle of base part 14. The size of the surface element 15 is coordinated such that its end faces rest on all base parts of the support profile 10 forming the peripheral frame. The clip bar 40 is then clipped onto the side wall 21 of the carrier profile 10, so that the latching hooks 47 of the clip bar 40 and the latching hooks 25 of the side wall 21 latch into one another. The elastic section 42 of the clip strip 40 lies against the surface element and, as can be seen in FIG. 4, is slightly bent back like the holding lip 22. As a result, the holding lip 22 and the leg 41 fix the surface element 15 through their respective elastic sections 24 and 42, respectively. Due to the elastic sections, it is also easily possible to use surface elements with a different thickness of z. B. 1.5 mm to 8 mm with the same device 11 to fix. In order to ensure simple mounting of the clip strip 40 on the carrier profile 10, the surface 13 of the base part 14 must be at least equal to or higher than the upper edge of the side wall 21 and thus higher than or equal to the Ras connection formed by the two latching hooks 25 and 47 his. The clip bar 40 can be easily placed on the side wall 21. The forces acting on the device 11 through the surface element 15 are derived via the side wall 21 of the carrier profile 10 or the extension 45 of the clip strip 40 onto the sections 18 and 19 of the carrier profile. Furthermore, there is a flow of force from the base part 14 through the legs 31, 32 to the carrier 34.

With simple means such. B. a screwdriver, both the clip strip 40 from the carrier profile 10 and the carrier profile 10 can be removed from the carrier 34 by simply loosening the respective locking connections. As a result, a damaged pane can be replaced in a simple manner without damage to the wall in which the carrier is installed.

5 shows a modification of the latching connection between the support profile and the clip strip. In contrast to the previous exemplary embodiment of the clip strip according to FIG. 3, the latching hook 47a on the extension 44a is not arranged on the side facing the other extension 45a, but on the side facing away. This results in a two-part design of the side wall of the carrier profile 10a. For this purpose, the carrier profile 10a has an outer extension 50 which projects between the two extensions 44a and 45a of the clip strip 40a and on which the extension 45a is at least partially supported. Furthermore, a second extension 51 is present on the carrier profile 10, which extends parallel to the first extension 50 and is at a distance from the latter. Furthermore, the second shoulder 51 has a latching hook 52 on the side facing the first extension 50, so that the extension 44a of the clip strip 40a projects between the two extensions 51, 50 of the carrier profile and the two latching hooks 47a and 52 lock into one another. The rest of the construction of both the clip strip as well the support profile corresponds to the construction shown in Figures 1 to 4.
